IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 160,067, dated February23, 1875 application filed' September 21, 1874.

To allvwhom it may concern:

Be it known that I, J ONATEAN W. WATER- MAN, of Oregon, in the county ofDane and State of Wisconsin, have invented a new and valuableImprovement in Lamp Extinguishers and Burners; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure l of the drawings is a representation of a front view of mydevice, showing the burner with top dome raised, the air-tube, &c. Fig 2is a section view of the same with dome down, and showing the operationofthe lever and sliding sleeve. Fig. 3 is a top view, showing therelative positions of the wick-tube, sliding sleeve, and weighted leverover the perforated plate, the top of the burner being oif. Fig. 4 is aperspective view of the sliding sleeve, showing the form oftheprojecting lugs upon the flattened sides of said sleeve.

My invention is a lamp-extinguisher; and consists in the novelconstruction and operation of the same in combination with a burner, ashereinafter described, and herewith shown,

for the purpose of readily, quickly, and conveniently extinguishing theflame of a kerosenelamp, and thereby prevent any chance of eX- plosionby theusual mode of blowing up or down ythe lamp-chimney to put out thelight.

embraces the following peculiar m "features:` imieffound the usualwick-tu be is formed an easily-sliding sleeve, moving vertically overthe outside surface of said tube, said sleeve provided on each of itstwo opposite iiat sides with a wedge-shaped flange or lug, the point ofthe wedge downward; a double-armed or k `forked. lever, each arm orprong weighted at check to the further upward movement of said sleeve; aperforated plate reversed from the usual manner, or turned with itsconcave surface upward; and, finally, the air-tube, reaching into theglobe alongside ofthe wick-tube, is cut off at its upper end flush withthe top ofthe screw-plate oftheburner, leavinga space between the top ofsaid air-tube and the bottoni of the said perforated plate, all of whichand their purposes are hereinafter more fully described, and illustratedby the accompanying drawings, in which the same letters designateidentical parts of the device in the different figures, respectively.

The letter A represents the hinged donie oftheburneroftheusualkerosene-lamp; Within and below said dome, and aroundthe usual wick-tube a, is fitted a metallic sleeve, B, so formed as toslide easily and vertically upon the outside surface of said wick-tube,and with its lower edge resting upon the top of the perforated plate bwhen its upper edge is iiush with the top of the wick-tube, for thepurpose of providing a longer sleeve than usual, with which, whensuddenly raised, to more completely and quickly smother and put out theflame of the burning wick. Upon the outside of each opposite andflattened surface of said sliding sleeve is securely and suitablyattached a wedge-shaped lug, G, as shown in the drawings, said lugshaving their projecting edges, c, inclining each toward its downwardpoint or verge, at d. The letter D represents the forked lever, made ofsuitable-sized wire, and bent into the form shown in the drawings. Thislever is thus formed into a handle and a fork with two prongs, whichprongs are thrust each through a hole, e, made in the rim E of theburner O, just below the said hinged dome A, and opposite to one of thesaid points d of the anges O, for the purpose ot' making said holes thepivotingpoints of the fulcrum of said lever. The said prongs are againtwisted at i, each over the other, after being passed, as aforesaid,through the holes c, for the purpose of keeping the lever from slidingout of proper position when working. The ends of each prong of saidlever are suitably Weighted, to cause the said weighted ends to quicklyfall back into place when the handle is let go; and the upper portion oredge of each weight Fis so beveled or inclined as to correspond with theinclined edge of its contiguous lug C when the aforesaid sliding sleeveB is raised sufciently (by the sliding of the prongs of said lever Dunderneath the points or verges d of said wedge-lugs) to press saidWeights F against said edges c of said lugs, and thereby serve to checkthe further upward motion of said sleeve B, and prevent it from beingthrown from the wiclctube when the lever is suddenly moved. Theperforated plate B differs in its adjustment in my device from thatusually adopted, as it is reversed, or with its concave side turnedupward instead of downward, for the purpose of allowing space for agreater length, as aforesaid, to the sliding sleeve B. The letter mrepresents the air-tube, leading from the top of the screw-plate n downalongside of the wick-tube to the bottom of said screw, and into theinterior of the lamp, sufficient space being left open to the outer airbetween the top of said air-tube and the bottom of the perforated plateb to allow said air to pass freely down the said tube into the lamp, forthe purpose of supplying the vacuum created by co1nbustion and theconstant siphon action of the iiaining wick, and yet of preventing anygas which might arise through the tube from coming in contact with ornear the iiame, even should air from any cause be blown down thelamp-chimney while the lamp is alight.

The operation of the extinguishing part of my device, described asaforesaid, is as follows: The lamp being alight, the thumb or n ger ispressed down upon the handle of the lever D, which causes the weightedends of the lever to rise, which in turn, by the sliding action of theprongs of the fork of said lever underneath the points d of the lugs C,rapidly lifts the sliding sleeve B, which again in its turn easily andquickly smothers and extinguishes the flame. The instant that thepressure upon the lever-handle is removed, the weighted ends fall, andthe sliding sleeve also falls, being additionally weighted by the lugsG. Thus the extinguisher is always ready for action, and easily andefficiently operated; therefore,

What I claim as my invention, and desire to secure by Letters Patent,is-

In a lamp-burner, O, the combination of the sliding sleeve B with theweighting wedgeshaped lugs C, having their projecting edges, c,inclining each toward a downward point, d, and the bent, twisted,forked, and bevel weighted lever D, substantially as and for thepurposes specied.

In testimony that I claim the above I have hereunto subscribed my namein the presence -of two witnesses.
